Worshippers hold up a banner reading "We love Benedikt" as they wait for the beginning of a mass to be held by Pope Benedict XVI on the grounds of the airport in Freiburg, southern Germany, on September 25, 2011, on the last day of the Pontiff's first state visit to his native Germany. The 84-year old pope, German born Joseph Ratzinger, has a packed program, with 18 sermons and speeches planned for his four-day trip to Berlin, Erfurt in the ex-German Democratic Republic and Freiburg.
